I got half life TFC and a gf4 mx440se like a un-made gf4 mx430 anyway. On myradeon 7200 sdram i get 100fps STEADY but wi th card im getting 72 steady ,maybe refresh dunno. Also on quake3 arena i get 120-125 steady fps on radeon but on this sdram gf440mxse i get hardly 100 like 72. I dunno why but they are a good card so i think cs will run fine, you want lag @ all unless ur cpu is slow.
